Description: NCL-C50 reacts with human cytokeratin intermediate filament proteins of 58kD and 45kD, identified as cytokeratins 5 and 18, respectively. Cytokeratin 5 is expressed by basal cells and suprabasal cells of stratified epithelium. Cytokeratin 18 is expressed by simple epithelial cells, including ductal and glandular epithelia.
